How do you solve cos x- sin^2x- 1

1 answer:

6 0

Sin(A + B) = sin(2x + x) = 1/2
sin(3x) = 1/2 
3x = sin^(-1)[1/2] 
3x = pi/6 , 5pi/6 ...etc 
x = pi/18 , 5pi/18 ...etc

hope that helped

What is the distance between points S and U if S is 2, 1 and U is 6, 8

balandron [24]

The distance formula is:

D = sqrt((x2-x1)^2 + (y2-y1)^2)

D= sqrt ((6-2)^2 + (8-1)^2)

D = sqrt(4^2 + 7^2)

D = sqrt( 16 + 49)

D = sqrt(65)

D = 8.06

Rounded to the beat tenth = 8.1 units.

The answer is C. 8.1 units

6(m-1)=3(3m+5) what does m=

love history [14]

Answer:

m = - 7

Step-by-step explanation:

Given

6(m - 1) = 3(3m + 5) ← distribute parenthesis on both sides

6m - 6 = 9m + 15 ( subtract 9m from both sides )

- 3m - 6 = 15 ( add 6 to both sides )

- 3m = 21 ( divide both sides by - 3 )

m = - 7

Using fluorescent imaging techniques, researchers observed that the position of binding sites on HIV peptides is approximately N

konstantin123 [22]

Answer:

The values is

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 2.45$

The standard deviation is $\sigma = 0.35 \ mi$

The random value is $x = 2.03$

The standardized score for a binding site position of 2.03 microns is mathematically represented as

$z-score = \frac{x - \mu}{ \sigma }$

=> $z-score = \frac{2.03 - 2.45}{ 0.35}$

=> $z-score = -1.2$
